Most of TI’s reports provide information on the methodology used. The methodology varies according to the subject of each report. Some reports are mainly based on interviews (see, for example, TI: People's Experiences of Corruption: Implications for Business in South-East Asia, 2019, p. 32), others focus on desk-research of publicly available material such as laws and legal cases, official documents, media articles and specialised literature (see, for example, TI: Examining State Capture, December 2020, p. 8). Other reports prefer a more quantitative approach, accessing primarily “publicly available material” (such as websites) and complimenting the information with follow-up interviews (TI: Protecting Climate Finance, 2014, p. 7).
